PACIFIC TANK COMPANY 



Leaching Tanks 




These tanks are made with vertical sides to allow the sat- 
urated ore to settle uniformly, instead of' settling away from the 
sides, which could not be avoided in tapering tanks. 

The general demand is for shallow leaching tanks with from 
three feet to eight feet inside depth and proportionately larger di- 
ameter, because the leaching capacity increases as per area of 
tank bottom. 

The average ore. after crushing, requires 25 cubic feet space 
to the ton and capacities of leaching tanks are figured accord- 
ingly.

PACIFIC TANK COMPANY 



Gold Storage Tanks 




These tanks are of special benefit in connection with cyanide 
plants where the solution, as it comes from the leaching tanks, is 
not clear, showing that such solution holds vegetable matter and 
fine slime in suspension ; in order to allow them to settle, the in- 
let pipe discharges near the bottom of the tank and the clear 
solution is drawn off at the top by means of a floating hose. 



TESTIMONIAL 

Olympia. Wash., Aug. 7, 1905. 
Pacific Tank Co., 

Olympia. Wash., 
Gentlemen: We have in use three or four fir tanks. They have been 
in position from two to ten years. In size they are from 10,000 to 25.000 
gallons. They are perfectly tight, are not checked, and show no signs 
of wear in any way. If we put in any new tanks they will be of fir. Of 
course the order would be given to a firm like yours who understand 
manufacturing tanks. 

Yours very truly. 

Olympia Lumber Co., 
(Signed) C. S. Eaton. Sec. Treas.

Sand Filter Bottoms 



Style "E" 




Weight, 4 pounds per square foot 

In some localities this filter is very much used. It consists 
of triangular slats, approximately 3"x 3"x 3". resting on regular 
crozed sill pieces. 

The spaces between the slats are filled with gravel, sand or 
quartz, level with the upper edge, and filter cloths are not 
needed in connection with them. 

This filter is highly recommended for copper leaching.

Description of Lathe 

During the past year we have made several important improvements in our Zinc 
Lathes, and discontinued to manufacture the Lathes formerly listed as No. 1 and No. 2. 
Our improved Lathes will now be known as No. 3 and No. 4, and superior to any 
machine on the market for cutting zinc shavings. 

The working parts of the No. 3 Lathe are on the front part of the machine. The 
cutting tool is larger and more easily adjusted. The mandril is 6" in diameter, cast with 
a hollow center, allowing a free circulation of air, preventing the zinc from over-heating. 
The shavings when cut, fall by gravity from the cutting tool to the floor. The machine 
is designed to cut three (3) thicknesses of shavings, 500, S00 and 1600 to the inch. This 
is accomplished by adjusting the eccentric so that the pawl will take 1, 2 or 3 notches 
in the ratchet wheel. 



DIRECTIONS FOR INSTALLING AND OPERATING THE 
HAMPTON IMPROVED ZINC LATHE 

Upon receipt of Lathe, unpack and attach legs (which in case of No. 3 Lathe are 
shipped in separate package) to the bed plate of Lathe by inserting 4 draw bolts through 
the legs and into the bed plate. 

Fasten legs to floor, which should be rigid and as free from vibration as possible. 

Lathe should be set so belt will pull from side, and a good length of belt should 
be used. 

The Lathe should be elevated so the shavings will have a vertical drop of about 6' ; 
in other words, set the Lathe on the second floor, or platform, and cut a hole for 
shavings to drop to receptacle below. This weight of shavings will prevent them from 
winding around the mandril. 

After the Lathe is in position and ready to run, thoroughly oil and allow same to 
run for a short time before winding on supply of zinc. 

When Lathe is in good running order and well cleaned, wrap a piece of heavy paper 
around the mandril and insert the first sheet of zinc in slot, winding it tightly, and just 
before the end of sheet is reached insert another sheet under the end of the first, con- 
tinuing this until S or 9 sheets have been placed on the mandril. Hold zinc in place by 
binding with two (2) pieces of wire! 

The machine is now ready to operate and care should be taken not to allow the 
cutting tool to come in contact with the mandril. If the lathe chatters, the power should 
at once be turned off and cutting tool re-ground. One or more tools should be ground 
and kept ready to take the place of a dull one. 

After loading the mandril, be sure and set the safety spring at the left-hand side of 
machine so the trip will throw the pawl out of the ratchet wheel and prevent the tool 
from cutting into the flange at end of, mandril. 

Be careful and grind the cutting tools on same angles as those furnished with ma- 
chine. Do not let your machinist experiment with the Lathe, with a view of improving 
same, as we have already done this; and as zinc is very hard to turn into shavings, we 
believe the machine, as now constructed, is as good as a zinc lathe can be made.

TESTIMONIAL 

Ouray, Colo., Jan. 22, 1902. 
The Pacific Tank Company, 
San Francisco, Cal. 
Gentlemen: I have to thank you for your valuable catalog No. 3, 
which I received today. It contains much valuable information, for 
which I am very grateful. 

The nine Redwood Tanks we purchased from you some time back 
have given the greatest satisfaction, and though some of them are in 
the open, exposed to the weather, they are all entirely free from leakage. 
We have also some eighteen Steel Tanks in service, as Leaching, Gold 
Solution, Sump and Storage Vats, and your wood tanks have been equally 
as satisfactory. On your Zinc Lathe we are cutting some 130 pounds of 
shavings per day. We altered the feed to suit our purpose, and make a 
shaving 1/1800 inch in thickness. 

The zinc shav'ngs cost us 10 cents per pound here, and the lathe 
is doing good work for us. I would be glad to receive any new pub- 
lications from you whenever you issue them. 

Yours very truly, 

The Camp Bird Cyanide Works, 

(Signed) Godfrey Doveton.

For some time past we have been furnishing a great number 
of our Improved Round Pattern Iron Zinc Precipitation Boxes. 
It will be noticed that the box is made round instead of square. 
This avoids the necessity of filling out corners. 

The iron is thoroughly protected by acid-proof paint, and 
every box is fitted with a perforated iron shavings tray with 
handle. 

The price quoted is for each box forming one compartment 
and generally six or more boxes are used in series. 



Precipitation Barrels

We are in position to quote upon Precipitation Barrels when 
customers desire to use them instead of our Standard Wooden 
or Round Iron Zinc Boxes. When requiring price on barrels, 
please specify size and style desired.

Description of Zinc Boxes 

40 we list a few standard sizes of Wooden Zinc 
instruct precipitation boxes in accordance 
with specifications submitted by our customers. 

In tl m of our standard sizes, we aim at deep 

compartments to compel the solution to pass through a thick 
inc shavings. The boxes are made very durable and 
arc held together by iron rods which pass vertically and hori- 
zontally through the wood. By using this construction it can 
lie solution cannot reach the iron rods 
which hold the box together. The bottom has a slope of 1" 
toward the discbarge. 

All compartments are furnished with improved screen shaving 
trays. 

At the lowest corner of each compartment will be found a 
rubber c m discharge plug, with screw flange and nip- 

ple, to facilitate removing the product from the box at the time 
of clean-up. 

The above does not apply to single compartment sheet-iron 
boxes shown on page 38.

Speed of Centrifugal Pumps 

Centrifugal pumps should be run at the speed shown in the 
following table for any required elevation. 

If a long line of pipe is used on the suction or discharge, the 
pumps should be run at a higher speed to overcome the friction 
of the water in the pipe, or larger pipe should be used. 

In estimating the speed necessary for any pump, special care 
should be taken to provide for this friction loss, and if this is 
not done, the amount of water discharged will be greatly dim- 
inished.

Pumps of different makes are run at different speeds to de- 
liver the same amount of water. 

A simple rule for finding, the speed of a centrifugal pump for 
any given height is as follows : Multiply the square root of the 
head, in feet, by 500, and then add 500 ; this result gives the 
circumferential speed of the. pump runner in feet per minute, and, 
by dividing it by the circumference of the runner, in feet, will 
give the number of revolutions the pump must run per minute.

;id experience with pumps to be used for handling sand and slime, 
that rigidity and durability are the prime features required in a pump for this 
work. This naturally leads to favoring a design of pump that has interchangeable wear- 
arts, and that these parts can be quickly and cheaply renewed. 
These features were carefully considered in the designing of this pump. 
The base and bearing stands are built up and cast in one solid piece. The bearings 
are both bored at one setting, thus assuring perfect alignment. 

The bearings are made of cast iron, turned on the outside and babbited and bored to 
fit I he shaft. 

outboard bearing contains an oil well and two ring oilers, which furnish ample 
"i ication for the hearing. 
The inboard bearing is fitted with one lubricating ring, a water well, and grooved 

intuiting clear water for lubricatiori. 

The impellor is of an improved enclosed type of heavy section, so designed that the 

Hot subject to gnnt wear being the point of entrance of the liquid. At 

loint, the impellor, the pump casing and side plates are fitted with interchangeable 

. 

The rings on the impellor are recessed t < » pass over the projecting ring on the side 

suction elbow. The velocity of the liquid being slightly accelerated at this 

lelivery into the center of the moving impellor with a minimum of wear. 

The other part of the pump subject to great wear is the periphery of the scroll 

iikcn care of by means "f a series of cast iron or steel segments neatly 

i in the collection chamber of the pump and -held in place by means of bolts which 

i lie outside. 
Bj mil allowing these liners to remain in the pump until entirely worn down, but 
replacing with new ones after a reasonable amount of wear, insures the pump being 
illy indestructable.

Agitation 

By Centrifugal Pump 




Code Name, LAUDIB 

This arrangement is used at many cyanide plants, partic- 
ularly with the agitation of slime in connection with decantation 
or. filter pressing. I hie advantage is that agitation can be read- 
ily started even if the material is settled compactly on the 
bottom of the tank, because the suction pipe being connected 
b\ a loose elbow, can, be raised from the bottom to the top of 
charge, suction started, and as the material loosens up, the 
weight of the pipe will cause it to gradually settle until finally 
ii suction takes place at the bottom of the tank. 

Price will be furnished upon application for tank complete 
as illustrated above. State size tank required.

Automatic Distributors 

HE automatic distributor illustrated on the following 
page is intended to take the tailings as they come 
direct from the stamps and distribute them evenly 
over the entire area of the tank. 

These distributors are manufactured in two types, 
one known as the overhead automatic distributor and the other 
as the supported or standpipe type. 

The overhead distributor is mounted on a track, making it 
possible to transfer from one leaching vat to another, thereby 
saving the expense of having one distributor for each vat. Where 
it is not practical to use the overhead distributor, the sup- 
ported or standpipe distributor can be used. 

These distributors consist of a hopper which receives the tail- 
ings and discharge pipes which distributes them. 

The pipe extensions are of different lengths in order to dis- 
tribute the tailings over the entire surface of the tank. 

In the construction of this distributor, we have adhered t> > 
the general principle of the well-known Butters Type, with the 
exception that the one manufactured by us revolves on ball bear- 
ings, making it much more effective and easily operated.

As stated on page 55, it is only, in special cases that Style "C" or "D" 
distributors are used, because a separate distributor must be ordered for 
each leaching tank, while one distributor of the style described on page 
55 will answer for any number of tanks. 

When ordering distributors, it is necessary to specify the amount of 
tailings per hour that will pass through the distributor, in order that the 
correct size of piping may be furnished. Also give inside diameter of tank.

Code Name, MADEMO 
This style of classifier is known as the Cone Classifier, and is one of the most 
nt types of hjSraulic classifiers that can be used for the separation of sand and 
slime. The pulp as it comes from the battery is received in the small hopper at the top 
of the classifier, which discharges it near the bottom of the cone, where it meets the up- 
rising current of water. The sand, being heavier, naturally sinks to the bottom, and 
slime, being of much lighter gravity, is held in suspension and overflows into a circular 
tier. !• rom this point it is carried to the slime plant, the sand going direct from the 
bottom of the cone to the sand plant. The above classifier is 3' diameter x 3' stave, but 
we can make them any desired size to order.

51 ipping Weight, 150 lbs. 



List Price, y4u.no 



The above cut illustrates our latest design of a small Cyanide Plant for assaying 
purposes, having a capacity of from one hundred to two hundred pounds of ore. 

The small tank shown at the highest elevation is to be used as a Solution Tank, 
while the two tanks just below it are intended for Leaching Tanks, and are fitted com- 
plete with False Bottoms and Duck Filter Cloths. The Gold Storage Tank is directly 
under the Leaching Tanks, and below this the Zinc Precipitation Boxes; these boxes 
are arranged in units so that any number from one to six can be used in making a test. 

The piping is so arranged that the solution can be fed to either the top or bottom 
of Leaching Tanks. 

We have recently shipped a number of these new style plants, and from reports 
received, our customers are highly pleased with the results obtained.

The Decantation Process 

Is principally used for extracting values from slime which 
cannot be leached on account of the slime forming an impervious 
bed. Therefore the slime is agitated by means of a centrifugal 
pump attached to the bottom of the tank, and discharging into 
the top, as illustrated on page 49, or by mechanical agitators or 
air lifts. When all values have been extracted, the slime is al- 
lowed to settle, and clear solution is drawn off from the top of 
the tank and led into zinc boxes. The slime is next subjected 
to several washes, with a repetition of agitation, settling and 
drawing off of clear solution. 

Decantation is a slow process and requires a great quantity 
of water for the separate washings, and for this reason Filter 
Pressing is often substituted for Decantation. 

In Filter Pressing there is only one agitation, which is dis- 
continued as soon as the values are absorbed by the solution. 




The next step is to force the contents of the tank into a Filter 
Press or Filter Leaves, for the separation of solution and solids. 

Where a straight Percolation Process cannot be used on ac- 
count of excess of slime, an experienced cyanide man will al- 
ways aim to separate just enough slime to allow the remainder 
to be percolated. It is often found that from 25% to 35% of 
slime may remain with the sands and still be treated by per- 
colation. 

A great deal of attention is being paid at the present time 
to separating solution from slime by Patent Filter Presses. 
There are several of these Patent Presses on the market, prin- 
cipal among them being the BUTTERS PATENT FILTERS. 
For additional information in reference to this particular pro- 
cess, see page 79. We bespeak great success for this method 
of separating solution from slime, as we know of several plants 
being successfully operated at the present time. We are pre- 
pared to quote prices and submit specifications for complete 
plant, including the Butters Filter Process.

The Butters Patent Vacuum Filter 

Code Name, NOCIVE 

One of the most difficult operations in the extraction of gol<i and 
silver by the Cyanide Process is the treatment of the slime. 

In addition to the ex| on, circulation, pumping and 

jsary for satisfactory extraction, the mechanical condition of the 
slime is usually such that it gives trouble in settlement for decanta- 
tion. the subsidence being so slow that the amount of solution recovei 
in this is often not i make the decantation process a practical 

success. The problem of separation of the solution from the slime 
solved by the invention of the Butters Patent Filter. 




The Butters Patent Vacuum Filter has been in use for over three 
years, and has proven an unqualified success. A few of the principal 
features that have resulted in its general adoption by the principal 
mining companies of the United States and Mexico are: 

1. The complete recovery of soluble values. 

2. The small amount of wash, either of weak solution or water to make this 
recovery. 

3. The conservation of water, where water supply is limited, the residue (contain- 
ing no more than 35% of moisture that carries no cyanide to poison the creeks) can be 
removed by cars or conveyor. 

4. AH the water that is introduced into the plant for the purpose of maintaining a 
normal quantity of circulating solutions, comes in through the filters, doing effective work. 

5. There is no excess of solution to throw away. 

6. There is a minimum quantity of solution containing maximum values for pre- 
cipitation, thereby necessitating only a small fraction of the zinc box capacity that would 
be necessary with the bulky decantation proo 

7 \ great saving in treatment tankage; as the valuable solutions are recovered 
immediately after treatment and the residue gotten out of the way at once, no time being 
lost ui settling and decanting, the treatment tank capacity is only that necessary for 

S. The ease and simplicity of operation. One unskilled man per shift will handle

a thicker layer than the finer, maintaining an even permeability of the

washing depends upon the character and thickness of the cake, the

nig in number upon the capacity desired, a contain- 
ing box and a system of pulp, water solution and vacuum pumps, with 
vats, pipes and valves, which may be arranged in any one of the dif- 
ferent systems, i. e. — gravity, semi-gravity or pumping; the semi-gravity 
being the preferred system. 

The pumping system is especially adapted to flat sites, where the 
treatment stock tanks, filter boxes and precipitation, may be on one 
level. 

The gravity system is best where electric power is bought at peak 
load rating, as the pumps are smaller. However, the total power con- 
sumed will be about the same for either system. 

There arc many improved features, such as special fittings, valves, 
etc., that greatly add to the simplicity of operation, and reduces power 
consumed. All the appliances are manufactured by the Butters Patent 
mm Filter Company, and furnished to users of filter leaves at cost. 
Complete plans and working details, designed to suit local conditions 
are furnished, thus insuring the most economic installation and opera- 
tion, as well as the highest possible efficiency.

Hypo-Sulphite Plants 

The treatment of silver ores by Hypo-Sulphite solution is, with some variation, the 
principal process in use for the extraction of silver values, and the specifications for such 
plant call for Tanks of a size and shape similar to those used for the Cyanide Process, 
with the exception that the silver is precipitated in Circular Precipitation Tanks instead 
of Zinc Boxes, and sufficient tankage must be provided to keep the different solutions, 
as wash water, weak solution or strong solutions separate. The necessary tankage con- 
sists of 

Lixiviation Tanks Solution and Sump Tanks 

Precipitating Tanks Precipitating Tanks for Wash Water 

Storage Tanks for Precipitates Sodium Sulphite Tanks 

The following process has been recommended by A. R. Partridge, Mining and 
Metallurgical Engineer: 



Hypo-Sulphite Leaching 




T HAS been the usual practice where gold is contained in the silver bear- 
ing ores in considerable quantities, and in an arseno-pyrite especially, 
and where salt is cheap, to use as high as 12% of this chemical. There 
is a double advantage to be gained by doing this — the extractions will 
be high in gold as well as silver, and the resulting sulphides will be 
much cleaner and of higher grade. 

As a general rule it is a mistake to crush ore finer than to a No. 26 
mesh, which should be done dry if possible. The silver will be just as 
easily chloridized and the vat filtration greatly increased. 

The secret of good leaching rests in the roasting or chloridizing of 
the ore, the balance is mechanical. 

The best results have been attained with hand roasters. In constructing a roasting 
furnace, it is essential to observe proper proportions of grate area and area of rabbling 
doors to that of the flue. If these conditions are correct, and green wood is used as 
fuel, the losses by volatilization will be small. 

The best time to add the salt during the roasting operation depends on the ore 
entirely. Give the ore a comparatively short roast and place in a heap as soon as it is 
drawn from the furnace. These heaps should be of a size equivalent to the capacity of 
one vat, or to the amount of ore roasted in 24 hours. 

The heaps should be allowed to cool naturally for from 5 to 14 days, according to 
the size of the heaps, and when thoroughly cool, a little water should be sprinkled and 
the ore loaded into vats. 

Few superintendents of works realize the importance of cooling the ore in this man- 
ner. Chi or i nation continues steadily throughout the heap until cold ; also, the ore be- 
comes very spongy and enables the filtration to take place rapidly as well as more 
thoroughly, and there is less loss by rich' solution remaining in the ore after the final 
wash water is applied. 

When a vat is ready for receiving its charge, the duck filter bottom should be well 
rinsed in clear water and set in position. The outlet cocks should be closed and the 
vat filled one-quarter of its depth with clean water, and the unleached ore charged in 
the vat to within 8" or 10" of the top. If the ore contains many bases and it is charged 
dry in the vats, the filter bottom is liable to fill with crystallized salts and impair a free 
filtration during the leaching process. 

Fresh water is now run into the vat from the top (and preferably from a series of 
holes which are made in the Patent Non-Shrinking Tanks), the outlet cocks turned on, 
and the resulting liquid run into the base sulphide precipitating tanks. 



s-i

rally the first 1500 gallons of wash water will contain all the 
silver that will be dissolved in the wash water. The balance of the 
water is run to waste until there is no sign of precipitation whatever. 
When this takes place, the water is shut off, and the hypo solution to 
the strength of 1.8% Beaume allowed to run continuously over the ore 
and the silver precipitated in the silver precipitating vats 

If tin is carried on as above, it will take about 30 hours to 

treat a large vat of ore. and the extractions should average 93% of the 
silver contained in the ore, and 36% of the gold. 

If the tailings contain any appreciable quantity of gold, and it will 
still pay to extract it. a weak solution of cyanide will do it effectively 
and without any necessity of removing the tailings from the vat. All 
that is necessary is to give the tailings an extra long wash after the 
- leaching has been concluded. The cyanide solution is precipitated 
in zinc boxes in the usual manner. 

Use as a precipitant one part of caustic soda to two of sulphur. This 
article gives a much clearer and richer sulphide, and is more easily pre- 
pared, and if the wash water is properly gauged, it will maintain the 
strength of the hypo solution. When once the stock solution has been 
made to standard, hypo-sulphite of soda is not necessary. 

In adopting the above described method the precipitating vat capacity 
has to be large, but, on the other hand, the ore vats need not be so 
numerous, and on the whole will be more economical both in first cost 
of plant, as well as in the actual operation.

When silver ores carry an appreciable amount of gold values, it is 
often advisable to give such ores a cyanide treatment after the silver has 
been extracted by hypo-sulphite; this second leaching can be done in the 
same leaching tanks without rehandling of the ore, and the following 
items would be required in addition to above specifications:

The Hendryx Agitator 

GITATOR is designed for the rapid extraction 
of gold and silver from unseparated sand and slime 
by means of agitation and aeration in weak chemical 
solutions containing cyanide. The essential me- 
chanical feature of the agitator consists of a cylin- 
rical tank having a conical bottom. In the center of 
the tank is a circular well which extends nearly to the 
top and bottom, supported by braces from the side 
of the tank, and having a circular apron at the top, which slopes 
lually towards the circumference and permits the ore 
pulp solution, in flowing over it, to be spread out into a thin 
sheet and to absorb an abundance of free oxygen. In this well 
is a hollow shaft carrying a driving pulley near the top and a 
number of screw propellors or pulp solution lifting wings. The 
discharge valve is connected to a screw for opening and closing. 
A coil of pipe serves for raising the temperature of the charge 
by means of steam or hot water passing through it. The revo- 
lutions of the propellors in the well produce a strong upward 
current, thus resulting in a rapid and uniform circulation of the 
pulp upward to an aerating apron, where it spreads out into a 
thin sheet, losing its velocity and gently falling from the edge 
of the apron into the great mass of the ore pulp solution, where 
its velocity is again reduced, and then gently dropped down to 
the bottom of the agitator. 

The power required to operate a machine holding a charge of 
110 tons of ore pulp, containing two tons of solution to one of 
ore, is five horse-power, and the whole contents of the tank are 
brought up and over the aerating or distributing apron once in 
five or ten minutes, depending on the speed of the pump. 

The agitator is built in three sizes, designated as 8-foot, with 
a capacity of six tons of ore to the charge; 12-foot, with a 
capacity of seventeen tons of ore to the charge ; and 17-foot, with 
a capacity of thirty-five tons of ore to the charge; and they treat 
from two to eight charges in twenty-four hours. These figures 
are based on ores of average character.

Copper Leaching Processes 

MOST RECENT DEVELOPMENTS IN COPPER LEACHING 

F THE many leaching processes developed and proposed for the economi- 
cal extraction of Copper from Carbonate, Oxide and Silicate ores, when 
reduced to their simplest terms, involves the use of either a copper solv- 
ent acid such as Sulphuric Acid (Oil of Vitriol, H 2 SO.i), the one 
mainly used, as well as that of Hydrochloric (Muriatic Acid) and Sul- 
phurous Acid (SOz) for Siliceous ores, and ores devoid of great quantity 
of acid-consuming minerals, which are: Lime, Magnesia, Alumina and 
Iron Oxides or Carbonates. For ores with gangues of the latter type. 
Ammonia and its compounds is the more economical solvent to be 
recommended. 
To make a financial and economical success of the acid leaching processes in treat- 
ing oxidized copper ores, implies in most cases the erection of an acid works at the mill 
and local manufacture at the lowest possible cost of the acid required, such as Sulphuric 
Acid, for instance, direct from a cheap source of Sulphur or Pyrites. The buying of 
acid at commercial centers and freighting to iIil- mine and mill usually proves expensive 
and ends in failure from a money making point of view. 

To construct and install Acid Works at a Copper Leaching Plant requires an outlay 
of large sums of money, but it can be depended on and will be quickly repaid through 
the very cheap cost of the acid produced. 

The strength of acid solution usually to be applied cold is from 3% to 5% (Ha SO*). 
Hot solutions, while giving a more thorough and faster copper extraction, quite often 
result in excessive and cbstly acid consumption per ton of ore treated. 

Sulphide copper ores will, after roasting with or without salt, give very nice extrac- 
tions with plain water leaching, and in but few instances demand a slight addition of 
acid from an outside source; in other words, will not require the building of Acid Works 
at the Mill. 

PRECIPITATION 

The usual precipitant for copper out of acid solutions is iron in the form of either 
scrap, billets or rails. With compressed air agitation and careful work, the iron con- 
sumption ought not to be over 1 y 2 to 2 pounds iron for each pound cement copper 
obtained. 

Electrical precipitation requires 70 to 125 H. P. per 24 hours per ton (2000 lbs.) 
copper produced, is costly to install and requires great skill to operate. 

Sulphurous precipitation is effected by saturating the copper solution with sulphur 
gas (SOa) and heating under pressure in boilers lined with acid-proof linings similar in 
method to that used in wood pulp manufacture. 

The last two methods of precipitation (Electrical and Sulphurous) are to be ap- 
plied where iron is too expensive and electric power or sulphur material cheap. 

Bluestone or Copper Sulphate — In many cases it is possible to boil down the 
leached copper solution to the crystallizing point, 32° to 35° Be, and manufacture Blue- 
stone at the mill at nominal cost. Copper Sulphate always brings a better price than 
any other copper mill product. The manufacture of Copper Sulphate (Cu Sd 5 Ha O) 
entirely overcomes the use of any required precipitant for the copper. As the extraction 
of copper from the ore by means of acid solutions, is usually complete in a few hours, 
the leaching or agitating capacity of a copper leaching plant is several times greater than 
that of a Cyanide system. 

A typical copper leaching ore with acid solutions is a copper carbonate (Azurite, 
Malachite) in Sandstone gangue. Sandstone ores with a mixture of copper carbonates 
and glance (Cu 2 S), Cuprous Sulphide or Chalcocite must first be roasted to give a 
satisfactory copper extraction on leaching with Sulphuric Acid. 

Where the ores on account of presence of much lime (Ca C03) will, with Sulphuric 
Acid solutions in leaching, pack, cement and behave badly. It will be advisable to 
apply Muriatic Acid instead. The Muriatic Acid is also to be manufactured on the 
mill property and is to be preferred for the above reasons on account of forming very 
soluble compounds with the Lime Minerals. Electrical precipitation can be more con-

The Ammonia-Cyanide Process

further development in the use of Ammonia as a 

extraction of Ammonia soluble metals from ores and 

tailings In tins process KCN is added to the Ammonia solution to 

combine both the gold and silver extraction with the copper. In many 

■ices a preliminary leaching with dilute Ammonia to remove as 

much of the copper as possible, followed by weaker Ammonia Cyanide, 

may prove of great advantage on account of permitting a better con- 

thc gold and silver values in the subsequent gold and silver precipitates 

iced, 

rinciple involved in the process is that by adding KCN to Ammonia in the 
copper, Cupric Cyanide (Cu CN a ). with an excess of Copper Hydroxide 
tCu HOi), is formed in the Ammonia solution. 

is very stable and has important oxidizing qualities, as it rapidly 
withdraws oxygen from the atmosphere, which, as is well known, is of great value in 
ordinary Cyaniding. An Ammonia-Cupric Cyanide solution has gold and silver solvent 
equal to or greater than ordinary KCN, and can be used on ores and tailings free 
from copper where the Cyanide consumption has been due to Ferrous or other reducing 
salts. 

The Ammonia-Cyanide solution is generally prepared by dissolving 1 to 4 lbs. KCN 
in a ton of solution containing 1% NHg for every 1% copper present in the ore or tail- 
ings. In ordinary leaching tanks a stronger Ammonia solution than 1% cannot be recom- 
mended. The plant in most cases can be of simple construction similar to regular Cyanide* 
3, but the precipitation of the values differs greatly from Cyanide practices, since the 
is precipitated in specially constructed stills. 
A modification of the Ammonia-Cyanide Process can be used for treating Sulphide 
silver ores raw, thereby avoiding the expense and installation required in roasting of 
same. 



The Mosher-Ludlow Still 

was designed as the simplest and least expensive method in recovering metals, such as 
zinc or nickel in the Ammonia and Ammonia-Cyanide Processes. 

The still admits of a continuous boiling out arrangement whereby a precipitate is 
recovered of high percentage in copper at very low cost and small steam consumption. 

The advantage of continuous over intermittent boiling and precipitation is well un- 
derstood and does not require detailed explanation. 

This still fully utilizes the heat units of the waste hot boiled out solution and forms 
.hi Ammonia tight apparatus. 

A heat interchanger and cooling coil is included in the still and the system requires 
an am ption tank, a storage tank, leaching tanks, sump tank, and a settling 

■ -ipitates, etc. 

As will be seen from the illustration, the object is to use a still of smalt dimensions 
but proportional large capacity and minimum operating expense. 

The heat interchanger extracts the heat from the outgoing boiled out solution, which 
it imparts to the ingoing Ammonia solution. 

The cost of boiling solution, precipitating metals as oxide and recovery of Ammonia 
should not exceed $0.10 per ton of solution, figuring coal at $6.00 per ton or oil or wood 
at corresponding prices. 

The cost of attendance and repairs is figured at $0.10 per ton additional, making 
a total of $0.20 per ton. 

A still of 4' diameter and 10' in height is estimated to boil out the solutio 
1 00 tons of ore in 24 hours.

A Set of Sherman Classifying Tanks, 

Followed by a System of Fine-Ore Settling 

and De -watering Tanks 




HE accompanying cul shows a combined system of Sherman Classifying 
and De-watering Tanks. 

High up in the front ranks of the useful inventions that have con- 
tributed to the saving of t] metal, will always be recognized 
the Sherman System of Concentration. 

One of the very important features of this system is the thorough 
manner in which the pulp is classified and freed from an excess of water 
so that the various sized products are delivered each to its respective 
concentrating table with just the proper amount of water so that the 
best results in working can be secured. 

It is ;i well-known fact that when properly classified material is delivered to a con- 
centrating table for working, that the capacity and efficiency of the table is greatly in- 
over any work | ibl< on an unclassified product. 

The System of Fine-ore Settling and De-watering Tanks deals with that class of 
material, which is the undersize of ^ 200-mesh screen— generally termed slime. By 
means of this system all the fine ore or slime is settled and de-watered, thence delivered 
to slime table under best possible conditions for successful working. The system par- 
tially shown in cut requires four slime tables for the proper treatment of the settled 
and de-watered material from these sixteen tanks. 

The overflow water from this system of tanks is clear and can be used as wash 
water on the concentrating tables or for any other purpose about the mill. 

Some of the advantages of this combined System of Classification and Settling are 
a ■■■ Fi 'Hows : 

FIRST — It is automatic in its working. 

Once the product is delivered to the first classifying tank of the series, no ma- 
chinery or power is needed. Once properly adjusted, the system requires but little 
attention. 

SECOND- -No wearing parts except the regulating plug, which is easily and cheaply 
replaced. Sets of these tanks are in operation that have treated 500,000 tons of ore and 
are in every respect .- - good today as when they were installed, the cost for maintenance 
being virtually nothing. 

THIRD — Large capacity and cheap cost of installation. 

FOURTH — A clean-cut separation of the various sized products, these being pro- 
perly de-watered, thus ena entratii .■ I ibb to produce best results in treatment 
of same. 

FIFTH- Working in connection with a Fine-ore Concentrating Table, a high saving 
of the very fine values can lie effected, thus saving by water concentration any values 
that will in from three to five minutes of time settle in still water.

SIXTH — Where economy of water is a consideration, it is possible to treat a ton 
of ore and not use more than 1000 lbs. or 1500 lbs. of water. The combined system 
offers many advantages in the treatment of gold ores by amalgamation, concentration 
and cyanidation. 

The classified material from each tank is drawn first to its respective amalgamation 
plate, thence from the amalgamation plate, as it passes to a concentrating table, thence on 
to the leaching vats for cyanide treatment. The classified material being freed from 
slime, plate amalgamation makes a much higher recovery of the free gold. 

After concentration the various classes of material can be kept separately as de- 
sired, even to the extent of keeping each of the seven classes by itself; thus the sand 
can be sent to the leaching vats in any manner that is most advantageous and the slime 
kept by itself for separate treatment by agitation. 

The process is in every respect ideal for the combined treatment of gold ores.

ROUND HOOPS 

7. If the tank is fitted with round hoops, decide first how many sections belong to 
each hoop. (This information is usually given a customer at the time shipment is made.) 

tie hoops are of larger diameter than others (for instance, if some are $£" and 
Uameter), the stronger hoops are to be used on the bottom of the tank at the 

of greatest pressure. Place the bottom hoop slightly below the center of the croze, 
the next hoop about 2" above, then gradually increase the space between the hoops 
until the top of the staves is reached. Two-thirds of the hoops should be placed on the 
lower half of the tank and no hoops spaced over 18" apart. Tanks fitted with round 
hoops are always made with straight sides. A few of the staves of each tank are marked 
showing where the hoops are to be placed. Where round hoops are used, it is advisable 
to seat the bottom hoop slightly into the wood. This can be done with a heavy hammer

it is often desirable to re-enforce the worn-out and leaky bot- 
toms with wooden bottoms. We therefore list the above sizes. 
and are prepared to furnish prices on special sizes upon applica- 
tion.

Open Water Heater, Condenser 
and Purifier 

Patent Applied for 




N THE preceding page we give an illustration of our 
Water Heater, Condenser and Purifier. Users will 
find this arrangement much cheaper than the iron 
heater usually supplied. It has a greater capacity at 
a very much less cost. The water comes into the 
Heater from the water supply, automatically gauged 
by a valve which keeps the water line always at the 
same point. The inlet supply is at the top, which 
allows the water to fall on a circular plate or table, that spreads 
it out and precipitates it to a second shelf or platform ; after 
passing over this, is allowed to run through holes to the bottom 
of the tank. The water is heated while descending, and comes in 
contact with the steam, which operation also condenses a certain 
amount of steam. AVater heated while in suspension is also 
purified and precipitates a certain amount of mineral matter upon 
the tables and into the tank. It often happens that three or 
four inches of this mineral substance is taken from the tables or 
bottom of the tank. If this mineral matter is allowed to reach 
the boilers, it forms on the tubes as a scale. 

The steam exhaust comes up through the tank, strikes a 
circular table above and escapes at the top, condensing to a cer- 
tain extent by coming in contact with the incoming water and 
striking th; upper surfaces and head of the tank. There is a 
flushing valve located near the bottom of the tank by which 
the water line can be raised about once a week to the top of 
the oil flushing funnels. This is done generally on Sunday, 
when the water is cool and the oil is floating on top. The oil 
will run into the funnels and out through the discharge pipe in 
a very short time. The surface of the water is skimmed free of 
oil which collects after coming through the exhaust from the 
engine. 

The boiler feed is located about twelve inches from the bot- 
tom of the tank, in order to draw water from the above sedi- 
ment line. The sediment should be drawn out occasionally 
through a three-inch opening at the bottom of the tank. This 
opening is kept closed with a wooden plug. 

Prices on heaters described above will be furnished upon application. 
We are prepared to quote prices on heaters of any size or capacity.

Reference Tables and Information 

Cyanides 

Cyanide of Potassium — KCX or KCy. 

Cyanide of Sodium— NaCN or NaCY. 

Cyanogen is composed of Carbon and Nitrogen, both together forming a composi- 
tion for which the chemical formula "Cy" is used, and which in its action is similar to 
one single element. 

Cyan(ogen)ide of Potassium and Cyan(ogen)ide of Sodium are combinations ol 
Cyanogen, with the basis Potassium and Sodium, respectively, the latter only acting as 
carriers for the Cyanogen. 

The action of the Cyanides in the extraction of gold and silver from their ores is 
based on the fact that they form with these precious metals soluble double compounds. 

TESTING CYANIDE 

The standard test in use is the so-called Nitrate of Silver test. This test is based on 
the fact that Cyanides form with Nitrate of Silver, when both are in solution, precipi- 
tates. In practice, a given quantity of Cyanide to be tested is dissolved in distilled water 
and titrated with one-tenth normal solution of Nitrate of Silver. As the curdy white 
precipitate, Cyanide of Silver, readily dissolves, as long as there is a surplus of Cyanide 
in the solution present, sufficient Nitrate of Silver solution is added until a permanent 
milky appearance is obtained. The addition of a small quantity of Chloride of bodium or 
Iodide of Potassium will help to give a more distinct reaction to the eye. Each cubic 
centimeter normal solution of Nitrate of Silver is equal to 0.013 grams pure Cyanide, 
so the exact strength of the Cyanide is easily ascertained. It is obvious that the strength 
of the Nitrate of Silver solution may be so adjusted as to save all further calculation, 
This formula is also useful for estimating the strength of Cyanide solution. 

Although Cyanide is poisonous, it can be safely handled, only care must be taken 
that it does not come in contact with sores and is not taken internally. 

ANTIDOTES FOR CYANIDE POISONING 

All Cyanides are deadly poisons, but the aqueous solutions used in practice are so 
dilute that there is little or no danger from the prussic acid evolved from them if the 
buildings are properly ventilated. 

Acids react on Cyanides, liberating Prussic Acid gas, which causes almost instant 
death when inhaled in a pure state. When diluted with air, it causes faintness, dizziness 
and a depressing frontal headache. 

Even very dilute solutions of Cyanide are poisonous when taken internally, and, 
when they come in contact with the skin, produce in some persons an eruption of painful 
red boils. . In cases where the hands and arms must be brought into contact with the 
solutions, rubber gloves, reaching over the elbows, should be provided for the workmen. 
Kaffir workmen are said to suffer no inconvenience, whatsoever from the contact of their 
skin with Cyanide solutions. 

Considering the extensive use of Cyanide, the number of fatal accidents is re- 
markably small. Up to the present time only one fatal case has been recorded in New 
Zealand. 

In case of accident from Cyanide poisoning, the following remedies are recom- 
mended: Put the patient into a hot bath, and apply cold water to his back and neck. 
In cases of internal poisoning, vomiting should be induced by emetics or by physical 

means. 

Freshly precipitated carbonate of iron, obtained by mixing equal quantities of 
Sodium Carbonate and Ferrous Sulphate, is recommended for internal use. 

If the poisoning is the result of inhaling Prussic Acid gas, it is advisable to make 
the patient inhale a small quantity of chlorine gas, ammonia or ether. The chlorine 
gas can be quickly made and applied by sprinkling a little bleaching powder on a piece 
of flannel moistened with Acetic Acid, and then holding the flannel to the nostrils of the 
patient.

pan or otherwise ; amalgamate the gold, volatilize the quicksilver ; weigh the 

button, and in column m table, eight, will be found the gold value of the 

Example.— Sample of sixty lbs. produces button weighing one grain the

How to Determine Purity of Potassium Cyanide 

Take a sample of the KCN to be tested across the thickness of the cake. Reduce 
this sample by crushing to a fine powder. To one gram of this reduced sample add 100 
c.c. of distilled water. Take 10 c.c. of this solution and titrate it with standard Silver 
Nitrate. The number of c.c. of Silver Nitrate required to produce a permanent pre- 
cipitate multiplied by five will give the percentage of KCN contained in sample. 

The above is not a determination of actual Cyanogen present, but a simple test to 
give working value of Cyanide. 

STRENGTH OF KCN SOLUTION 

To 1000 c.c. of distilled water add 6.535 grains of c.p. Silver Nitrate and standard- 
ize with a known strength of Cyanide solution. 

For determining the amount of Cyanide in solution, take 10 c.c. of the solution 
(measured in a pipette) and place it in a small beaker; titrate this with the Silver Ni- 
trate solution, until an opalescent precipitate appears. The number of c.c. of Silver 
Nitrate used in tritration will then equal the number of pounds of Cyanide in one ton 
of the solution. 

ACIDITY TEST 

Place fifty grams of pulp in a bottle suitable for agitating; add 25 c.c. of a deci- 
normal (N/10) caustic soda solution (as described further on) and 75 c.c. of water; 
agitate for an hour and filter off the solution. TitraU- 20 c.c. of this filtrate with a deci- 
normal (N/10) solution of Sulphuric Acid, using as an indicator Phenolphthalien or 
Methyl-Orange. 

Five minus the Burette reading, multiplied by 2. will give the number of pounds of 
lime necessary to add to each ton of ore to keep the Cyanide solution at the proper 
point of alkalinity. 

In connection with the above, lime is presumed to be 65" pure. 

It is advisable before making above acid test to agitate fifty grains of ore with 100 
c.c. of water, filter and try the filtrate with litmus paper. If this shows a strong re- 
action, there is a quantity of free acid present, which may be removed by a water wash. 

PREPARATION OF N/10 SULPHURIC ACID SOLUTION 
Add 30 c.c. concentrated c.p. Sulphuric Acid to a litre of distilled water; make 
determination of Sulphuric Acid and correct until solution is absolutely normal ; each c.c. 
of this solution then contains .049 grains of HaSO.j ; add 100 c.c. of this solution to 900 
c.c. of distilled water, and we have the N/10 solution, each c.c. of which contains .0049 
Sulphuric Acid. 

PREPARATION OF N/10 SODIUM HYDRATE SOLUTION 
Dissolve about 56 grains of pure Caustic Soda in 1000 c.c. of distilled water (this 
will give a solution slightly stronger than normal). Titrate this with the normal Sul- 
phuric Acid solution, using Litmus or Phenophth alien for an indicator; make corrections 
and titrate again until one c.c. of this solution is equivalent to one c.c. of Sulphuric 
Acid. Add to 100 c.c. of this solution 900 c.c. of distilled water and one c.c. of this 
N/10 solution will neutralize one c.c. of N/10 Sulphuric Acid solution. 

DETERMINATION OF SULPHUR IN H 2 S0 4 
Place in weighed platinum dish two grains, approximately, of recently heated Sodium 

Carbonate. Dissolve with a small amount of distilled water, cover and carefully add 25 

c.c. of Sulphuric Acid to be tested. 

Evaporate to dryness on water bath. Remove cover and dry at 180° in air bath to 

constant weight. 

In this process SO-! = 96 has displaced CO;j = ;60 ; the difference in weight of platinum 

dish and contents before and after adding Sulphuric Acid is proportionate to amount 

of H s SO* in the 25 c.c. Then (96—60) : 9S : : difference in weight : x (HJ.S04 in 25 

c.c). x-^25 = .049.

Amount of Gold and Silver in 
Cyanide Solution 

Alfred Chiddy's Method 

Add to four assay tons (or more) of the solution 10 c.c. of 10% 
solution of lead acetate; then 4 grams zinc shavings; boil a minute; add 
20 c.c. HCL (strong). When action has ceased, boil again and decant 
from the ball of spongy lead, which has been decanted a little with a 
glass rod, and wash same by decantation. Transfer to a piece of filter 
paper, roll into a compact ball and place (without drying) on a hot 
cupel in the muffle. 

It is best to .transfer the compact ball from the filter paper to a piece 
of c.p. lead foil and then cupel directly or scorify first, then cupel. 

Do not add all of the 20 c. c. HCL at once, as zinc may break up on 
account of violent action. 

Another Method 

Take a piece of c. p. lead foil and form a tray about 5" long, 2 l / 2 " 
wide and 3/j" deep, and evaporate in this tray from one to three assay 
tons of the solution Until dry, and then cupel the lead. 

It is seldom necessary to scorify the lead before cupelling, unless the 
solution is very foul.

Manufactured in sizes from 2 to 24 inches in diameter, joints 8 ft. 
upwards in length, and for pressures up to 400 ft. head. 

The staves for this pipe are made from clear, well-seasoned, or kiln- 
dried, redwood or fir. These staves are banded with heavily galvanized 
steel rod, further protected by being coated with hot asphaltum and tar. 
The banding is wound on the pipe under a tension that seats it slightly 
in the wood. The tension of the bands is maintained by means of a 
clip at the end of each joint, the band passing two or three times through 
this clip. The spacing and size of the band is determined by the pres- 
sure for which the pipe is manufactured. Thus the cost varies, but each 
class of pipe is made amply strong for the pressure for which it is 
constructed. 

The tenon ends of each joint of pipe are turned to closely fit the 
collars connecting these joints. Either cast-iron, wood or steel collars 
are used. In conveying acid or salt waters the wood collar is usually 
desired. 

Fittings of any description are furnished for tapping or connecting 
wood pipe with any other pipe or for the construction of any kind of 
a wood pipe system. 

For water works, irrigation, mines, sewers, hydraulic dredges, electric 
conduits and steam pipe casing this pipe cannot be surpassed. 

For complete information write to nearest office.
